WINDMILL.

Specification of Letters Patent.

Patented Jan. 26, 1909.

Application filed September 28, 1906. Serial No. 336,651.

T 0 all whom it may concern:

' Be it known that. I, ANASTASIOS MAoRIs, a citizen of the UnitedStates, residing at Juneau, in the District of Alaska, have inventedcertain new and useful Improvements in Windmills, of which the followingis a specification l. My invention relates to windmills; and ha for itsobject to so construct the same, that the parts composing the mill maybe easily and cheaply manufactured; and the structure readily assembled,when desired A further object is to so construct the vanes of the millthat the surface thereof may be in creased or decreased at pleasure; andthe controlling mechanism of said vanes be so constructed as to takeupshock due to constant change in the position of the same.

In the drawings forming a part of this specification, and in which likesymbols of reference represent corresponding parts in the several'viewszF igure 1 is an elevation of my device; Fig 2 a plan view of the same,on the line bb, Fig 1 Fig 3 a plan, on the line aa, Fig 1; Fig 4 avertical section of the main supporting shaft, on the line cc, Fig 1Fig. 5 a view of one of the vanes; and,

, Fig. 6 a View of one of the springs connected to the vanes.

1 represents the vertical standards of the main frame; 2 thecross-pieces at the top of same; and 3 the cross-pieces of the bottom ofthe structure.

4 are bars forming a supporting framework at the base of the mill, thesame being in turn supported on the cross-pieces 3; 5 shafts supportedby straps 6, the same supporting bear ings for the shafts; and 7 gearson said shafts, which mesh with each other and are adapted to beoperated by a crank 8. There are two of these shafts 5 one supported oneach side of the frame.

9 are pinions on the ends of shafts 5, the same meshing with rack-bars10, on rods 11; and 12 are guides for the rack-bars.

13 and 41 are sleeves riding on the main shaft 14 and revolvingtherewith and within ing from platforms 17; 22 vertical supportingbraces, connected to short supporting rods 23, and in turn connected tothe arms 21.

24 are the vanes of the device; 25 shafts supporting the same, saidshafts passing through the main shaft 14 and journaled in bearings inthe arms 23; 26 rods connected to the underside of platforms 17, andhaving their outer ends connected to short arms 23; and 27 are cushionson said rods 26, against which the vanes contact when in their uprightor operative position.

28 are counterbalances connected to the shafts 25 to balance the weightof the vanes; 29 cords connected to the vanes by screw eyes 30, andhaving" their outer endsconnected to springs 31, in boxings 32; and 33are nuts to adjust the tension of said springs. The object of thesprings is to take-up shock, and also to have a slight tendency to throwthe vanes out of operative position, or depress the same.

34 are staples on the vanes; 35 rings sliding on the same; 36 ropesconnected to the sides of the rings and passing over the pulleys 20; and37 openings in the vanes. 38 are 'shutters adapted to close the openingsin the vanes; said shutters sliding in ways 39 in the vanes; and 40 eyesin the shutters for reception'of screws or the like, to connect the sameto the shafts 25.

41 isa reciprocating sleeve at top of the main shaft 14, correspondingto sleeve 13 42 straps for reception of ears 43; 4:4: a lever connectedto said ears, and to. a fulcrum 49, the office of said lever being toraise sleeve 41 and with it the rods 16 to actuate the same and operatethe ropes, and thus open the shutters 38. The lower series of shuttersis operated by the crank 8, the pinions operating on the rack-barraising the poles 16 in a similar manner.

45 is a gear at the base of main shaft 14, and 46 a similar gear onshaft 47, the latter shaft applying the power where desired.

The operation of the device will be apparent from the foregoing :Thevanes being connected to the shafts eccent'rically, two thirds of theirsurface being above the shaft,

when acted upon by the wind assume a vertical position, buthaving-passed to the return position immediately falls, the weightstending to normally balance the same. When more power is desired on thevanes the shutters are closed, or if a reduction of power is desiredthey are opened by the manipulation of the crank 01'' lever, as desired.

Of course I may make my device with any number or size of vanes, and theseries may be increased to any number desired: ,The

upper series of vanes are disposed in a plane between, or atright-angles to thejlower.

The shafts of.the vanes go through the main shaft,,s'o that. as one endof the shaft is in opprative position the other is inoperative. 'l emill is, divided into independent sections, so that mills of more :than'twenty horse power may be built, and each section may be regulated byits owndevice, and in case one section is injured other. is unaffected.

" Having now fully described my invention,

. what I claim as new desire to secure by v Letters-Patent, is :-.1

, v1. In a windmill, a mainsupporting shaft,

connected to the same, vanes on the erated automatically by the Windvanes provided with openings and shutters adapted to close the o enings,cords having connection with the s utters, pulleys upon which the cordsoperate, radial arms supporting the pulleys,;and a series of rods towhich said ropes or cords are attached and adapted to .be operated. I Intestimony whereof I -a'ffix my signature presence of two witnesses.
